It can also show information about the video such as the amount of I/P/S/B-VOPs used, whether or not QPel/GMC were used, etc. Requires .NET Framework 2.0.

This tool is just what I've been looking for
one thing is there a way to use batch when processing multi files?



Sep 14, 2014 by Somethingelse- Version: 1.4.5 OS: Windows 7 64-bit Ease: 10/10 Functionality: 6/10 Value: 10/10 Overall: 8/10



this is a great tool, the only bad thing is that... I,m having trouble with avi high definition files.
they have more then 2 gigabytes, and I don,t think this tool supportīs it.

my files are usually in 720p resolution, e use divx plus converter to convert my mkv ( h264 )
to avi ( divx + ac3 or mp3 sound )
because my memup media player only supportīs avi hd files ( xvid or divx )
it doesn't supports h264

and i hould like to change the aspect ratio to 16:9 in ( avi hd )
but the tool gives me a error...

on regular 700mb, standard resolution avi files the program works fine.

i hope that someone improve this program, to keep track of modern high definition files.

xvid or divx support today up to 1920x1080 resolution, itīs a bloody shame, to see a movie with an aspect ratio of 2.35.1 in a 16:9 TV ( I see it, with black bars )

if the avi is on standard size and resolution I can easily change to full-screen 16:9
go to " display ar" choose 16:9 and click save file :-) ( no black bars )

this is a one of kind tool, congratulations to the author

This tool does have a CLI version so you can easily create a batch file and process
as many as you'd like. Check http://forum.doom9.org/showthread.php?t=117553

The main drawback is lack of queue function. Would be great to process hundreds of videos with one click, now each video mus be loaded separately. But anyway very useful tol.

I tried so many programs like abcavi to correct the aspect ratio of a downloaded avi file but without any success. Then I stumbled upon Mp4modifier and it did in 2 seconds flat what I have been trying for so many days. Just great.
